control: video frame capture + deterministic input-movie replay
Two socket features for building reproducible showcase clips:
- record start <path> [everyN] / record stop: append the RGB888 framebuffer of
each produced frame to a flat 'GBCV' capture file (downsample with everyN).
tools/gbgif.py turns it into a GIF (or PNG frames). Capture is decoupled from
wall-clock/turbo/frameskip, so timing is always correct.
- input play <path> [reset] / input stop: drive the joypad from a synthesized
TAS-style movie (text: '<frames> [buttons...]' per line), frame-locked so
replay is deterministic. 'reset' does an exact power-on (preserve cart
ROM+SRAM, zero all other state) so a movie replays byte-identically -- verified
by hashing two runs. tools/gbmovie.py is a Python builder for movies.
